Pending Acquisition by Thoma Bravo On September 22, 2025, we announced that PROS Holdings, Inc. entered into a definitive agreement to be acquired by Thoma Bravo L.P. in an all-cash transaction valued at approximately $1.4 billion, or $23.25 per share. The per-share merger consideration represents a premium of approximately 53.2% over PROS’s 30-day volume weighted average trading price as of the unaffected trading date of September 19, 2025. The transaction is subject to approval by PROS’s stockholders, regulatory approvals and other customary closing conditions, and is currently expected to close in the fourth quarter of 2025. In light of the pending transaction, PROS will not be hosting a third quarter earnings conference call and is suspending its practice of providing financial guidance. 1

Non-GAAP Financial Measures PROS has provided in this release certain non-GAAP financial measures, including non-GAAP gross profit and margin, non-GAAP subscription margin, non-GAAP income (loss) from operations or non-GAAP operating income (loss), subscription annual recurring revenue, adjusted EBITDA, free cash flow, non-GAAP tax rate, non-GAAP net income (loss), and non-GAAP earnings (loss) per share. PROS uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating PROS ongoing operational performance and cloud transition. Non-GAAP gross margin can be compared to gross margin which can be calculated from the condensed consolidated statements of income (loss) by dividing gross profit by total revenue. Non-GAAP gross margin is similarly calculated but first adds back to gross profit the portion of certain of the non- GAAP adjustments described below attributable to cost of revenue. Non-GAAP subscription margin can be compared to subscription margin which can be calculated from the condensed consolidated statements of income (loss) by dividing subscription gross profit (subscription revenue minus subscription cost) by subscription revenue. Non-GAAP subscription margin is similarly calculated but first subtracts out from subscription cost the portion of certain of the non-GAAP adjustments described below attributable to cost of subscription. These items and amounts are presented in the Supplemental Schedule of Non-GAAP Financial Measures. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure as detailed above. A reconciliation of GAAP financial measures to the non-GAAP financial measures has been provided in the tables included as part of this press release, and can be found, along with other financial information, in the investor relations portion of our website. PROS use of non-GAAP financial measures may not be consistent with the presentations by similar companies in PROS industry. PROS has also provided in this release certain forward-looking non-GAAP financial measures, including non-GAAP income (loss) from operations, subscription annual recurring revenue, non-GAAP earnings (loss) per share, adjusted EBITDA, free cash flow, non-GAAP tax rates, and calculated billings (collectively the "non-GAAP financial measures") as follows: Non-GAAP income (loss) from operations: Non-GAAP income (loss) from operations excludes the impact of share-based compensation, amortization of acquisition-related intangibles, severance and transaction costs. Non-GAAP income (loss) from operations excludes the following items from non-GAAP estimates: • Share-Based Compensation: Although share-based compensation is an important aspect of compensation for our employees and executives, our share-based compensation expense can vary because of changes in our stock price and market conditions at the time of grant, varying valuation methodologies, and the variety of award types. Since share-based compensation expense can vary for reasons that are generally unrelated to our performance during any particular 2
Page 3
period, we believe this could make it difficult for investors to compare our current financial results to previous and future periods. Therefore, we believe it is useful to exclude share-based compensation in order to better understand our business performance and allow investors to compare our operating results with peer companies. • Amortization of Acquisition-Related Intangibles: We view amortization of acquisition-related intangible assets, such as the amortization of the cost associated with an acquired company's research and development efforts, trade names, customer lists and customer relationships, as items arising from pre-acquisition activities determined at the time of an acquisition. While these intangible assets are continually evaluated for impairment, amortization of the cost of purchased intangibles is a static expense, one that is not typically affected by operations during any particular period. • Severance: Severance costs relate to the departure of our Chief Revenue Officer. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies. • Transaction costs: Transaction costs relate to the pending acquisition of PROS by Thoma Bravo L.P. announced in September 2025 and they include legal, accounting, financial advisory and other professional services fees. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies. Non-GAAP earnings (loss) per share: Non-GAAP net income (loss) excludes the items listed above as excluded from non-GAAP income (loss) from operations and also excludes amortization of debt premium and issuance costs, gain on debt extinguishment and the taxes related to these items and the items excluded from non-GAAP income (loss) from operations. Estimates of non-GAAP earnings (loss) per share are calculated by dividing estimates for non-GAAP net income (loss) by our estimate of weighted average shares outstanding for the future period. The weighted average shares outstanding used in the calculation of non-GAAP earnings (loss) per share exclude the impact of the 2027 convertible notes exchanged. In addition to the items listed above as excluded from non-GAAP income (loss) from operations, non-GAAP net income (loss) excludes the following items from non-GAAP estimates: • Amortization of Debt Premium and Issuance Costs: Amortization of debt premium and issuance costs are related to our convertible notes. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies. • Gain on Debt Extinguishment: Gain on debt extinguishment relates to the 2027 convertible notes exchange, a non-recurring transaction, during Q2 2025. These amounts are unrelated to our core performance during any particular period, and therefore, we believe it is useful to exclude these amounts in order to better understand our business performance and allow investors to compare our results with peer companies. • Taxes: We exclude the tax consequences associated with non-GAAP items to provide investors with a useful comparison of our operating results to prior periods and to our peer companies because such amounts can vary significantly. In the fourth quarter of 2014, we concluded that it is more likely than not that we will be unable to fully realize our deferred tax assets and accordingly, established a valuation allowance against those assets. The ongoing impact of the valuation allowance on our non-GAAP effective tax rate has been eliminated to allow investors to better understand our business performance and compare our operating results with peer companies. Subscription Annual Recurring Revenue: Subscription Annual Recurring Revenue ("subscription ARR") is used to assess the trajectory of our cloud business. Subscription ARR means, as of a specified date, the contracted subscription revenue, including contracts with a future start date, together with annualized overage fees incurred above contracted minimum transactions. Subscription ARR should be viewed independently of revenue and any other GAAP measure. Non-GAAP Tax Rate: The estimated non-GAAP effective tax rate adjusts the tax effect to quantify the impact of the excluded non-GAAP items. Adjusted EBITDA: Adjusted EBITDA is defined as GAAP net income (loss) before interest expense, provision for income taxes, depreciation and amortization, as adjusted to eliminate the effect of stock-based compensation cost, amortization of acquisition-related intangibles, depreciation and amortization, severance, transaction costs and capitalized internal-use software development costs. Adjusted EBITDA should not be considered as an alternative to net income (loss) as an indicator of our operating performance. 3
Page 4
Free Cash Flow: Free cash flow is a non-GAAP financial measure which is defined as net cash provided by (used in) operating activities, excluding severance and transaction costs, less capital expenditures and capitalized internal-use software development costs. Calculated Billings: Calculated billings is defined as total subscription, maintenance and support revenue plus the change in recurring deferred revenue in a given period. These non-GAAP estimates are not measurements of financial performance prepared in accordance with GAAP, and we are unable to reconcile these forward-looking non-GAAP financial measures to their directly comparable GAAP financial measures because the information described above which is needed to complete a reconciliation is unavailable at this time without unreasonable effort. Forward-looking Statements This press release contains forward-looking statements made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.
